TypeError in Acquisition.init() when running dcm2bids

[mtmmu88]

Description:
I am encountering a TypeError when trying to convert DICOM files to BIDS format using dcm2bids. The error message indicates that Acquisition.init() is missing 2 required positional arguments: 'datatype' and 'suffix'.
Steps to Reproduce:
Run dcm2niix to convert DICOM to NIfTI:
dcm2niix -z y -f %p_%s -o /home/zzc/gwx/SRS00004 /home/zzc/gwx/SRS00004
This step completes successfully.
Run dcm2bids:
dcm2bids -d /home/zzc/gwx/SRS00004 -p sub-01 -c /path/to/config.json --force_dcm2bids
This step fails with the following error:
TypeError: Acquisition.init() missing 2 required positional arguments: 'datatype' and 'suffix'
Expected Behavior:
I expect dcm2bids to successfully convert the DICOM files to BIDS format.

Actual Behavior:
The program crashes with a TypeError.

Environment:
OS: Linux-6.2.0-34-generic-x86_64-with-glibc2.35
Python version: 3.12.0
dcm2bids version: 3.1.1
dcm2niix version: v1.0.20230411
Additional Information:
I have tried simplifying the config.json to only include the SeriesDescription field, but the issue persists.

Here is my simplified config.json:
{
"descriptions": [
{
"dataType": "anat",
"modalityLabel": "T1w",
"criteria": {
"SeriesDescription": "OAx 3D T1BRAVO"
}
}
]
}
Any help would be greatly appreciated.
